Research: Gravitational Microlensing

Gravitational microlensing has proven to be an interesting tool for detecting
low-mass planets beyond 1 kpc. Furthermore the method is especially sensitive
for planets with semi-major axes of several AU. The PhD project comprises
participating in the search for extrasolar planets by following up potential
targets from the OGLE and MOA survey groups using Göttingen's 1.2-m MONET
robotic telescopes in Texas and South Africa, as well as the theoretical modeling
of anomalous microlensing events like the detectability of debris disks
around microlenses. In addition we are trying to extend existing
prioritization systems for being able to select the most promising planetary candidates.
